B) If the restriction(s) is (are) rejected, the number of eigenvalues will fall
C) Whether the restriction is supported by the data or not, the eigenvalues are likely to change at least slightly upon imposing the restriction(s)
D) All linear combinations of the cointegrating vectors are themselves cointegrating vectors
